Real-time ECG monitoring in swimmers
Research is being conducted into systems and methods that enable an electrocardiogram and a noise-correlated reference signal to be transmitted to an analysis computer whilst swimming, in order to determine the swimmer’s heart rate and heart rate variability in real time with a high degree of accuracy.

Brain impedance measurement
Intraoperative impedance spectroscopy measurement of the complex conductivity of brain tissue
Research is being conducted into measurement systems and analysis methods that enable both the conductivity and permittivity of brain tissue to be measured with high accuracy during surgery.
Collaborating partners: Max Planck Institute for Human Cognitive and Brain Sciences, Leipzig; Institute for Bioprocess and Analytical Measurement Technology (IBAM), Heiligenstadt; University of Leipzig; Technical University of Ilmenau; Sciospec Scientific Instruments GmbH
Publication: “A four-point measurement probe for brain tissue conductivity and permittivity characterisation”
Heart rate monitor
Optical heart rate sensor with wireless interface and adaptive motion interference suppression
Research is being conducted into how an optical heart rate sensor must be designed to minimise the effects of significant movement as effectively as possible. In addition to sensor design, research into new digital signal processing techniques plays a particularly important role. The aim is to determine the beat-to-beat heart rate of athletes engaged in vigorous exercise with a high degree of accuracy and to display it in real time on an analysis computer.

Ultrasonic flow measurement
Ultrasonic flow measurement of very low flow rates using the digital time-of-flight difference method
The precise, non-invasive measurement of minute flow rates in flexible tubing presents a major challenge in ultrasonic measurement technology. Research is being conducted into methods that enable the high-precision determination of time-of-flight differences in the picosecond range based on digital analytical signals.
